I just read the last couple of pages and had to verify what topic I am reading. Sounds like BDSM.
For the life of me I won't understand people who self inflict pain for no other reason but beauty. Our body is such a precious thing. It is so easy to damage it. We should treasure it. Although, I think we understand it only after it fails us, but usually it is too late to worry.
I guess my threshold is somewhere very near to Stitchawl's
